Stormy Weather


What causes a tornado to dissipate?

Just as the formation of tornadoes is not well understood, neither are the reason for why they disappear. One theory is that when colder air begins to flow out of the storm—the mesocyclone at the center of the storm becomes surrounded by cooler air—the tornado is robbed of sufficient energy and loses power. However, this is not a hard and fast rule, and cool air outflows have been observed that actually are followed by tornado formation.
